I do run wallyworld oil. But I change it after every hard run. Maybe that has something to do with it.... I guess there can be a lot of variables. I'll see if i can find that article online though, thanks!

Change your oil several times when you get it running all that metal is somewhere in your engine. Hopefully most is in the filter, but you do not want it tearing up the rods and mains hopefully it hasent allready because it dont take long.
